The airway tube 13 forms an outlet channel 14. The top end of the outer wall 12 is also provided with a mouthpiece portion 15. The user inhales the nebulised gas which passes through the airway 13 through the mouthpiece portion 15. The top end of the mouthpiece part 15 is provided with a sealing plug 16 for plugging the outlet of the airway tube 13, when the user uses the atomizer 100, the sealing plug 16 is pulled out, and after the use is finished, the sealing plug 16 is inserted into the airway tube 13 to seal the airway tube 13, so that impurities enter the airway tube 13. In this embodiment, the sealing plug 16 is a rubber plug. The outer side of the sealing plug 16 in contact with the airway tube 13 is provided with at least one radially outwardly extending rim 161, which rim 161 enables the sealing plug 16 to fit tightly against the airway tube 13, thereby improving the sealing effect of said sealing plug 16.

The bottom of the outer wall 12 of the liquid storage bin 1 forms an accommodating space, and the atomizing core assembly 2 is arranged in the accommodating space. Referring to fig. 3 to 5 together, the atomizing core assembly 2 includes an upper support 21, a lower support 22, and a heat generating assembly 23 disposed between the upper support 21 and the lower support 22. In this embodiment, the lower bracket 22 is clamped at the bottom end of the outer wall 12 of the reservoir 1. In this embodiment, the outer wall 12 is opened with a lateral opening near the bottom end thereof, and the lower bracket 22 is correspondingly provided with a clamping portion 221 protruding outward in the radial direction, and the clamping portion 221 can be clamped in the opening, so that the lower bracket 22 is installed on the liquid storage bin 1. Specifically, the lower holder 22 includes a bottom wall 222 and a side wall 223 extending axially upward from the outer periphery of the bottom wall 222. The bottom wall 222 and the side wall 223 form a housing space for housing the upper rack 21. Similarly, the upper bracket 21 is connected to the lower bracket 22 by means of a snap connection.

In this embodiment, the lower bracket 22 further includes a convex pillar 224 extending upward from the upper end of the sidewall 223 along the axial direction for connecting and fixing the upper bracket 21. The boss 224 is provided therein with a lateral coupling hole 225, and the upper bracket 21 is correspondingly provided with a projection 226 coupled with the coupling hole 225, so that the upper bracket 21 is mounted on the lower bracket 22 by the cooperation of the projection 226 and the coupling hole 225.

The upper bracket 21 in this embodiment includes a substantially annular base portion 227 and a bridge portion 228 connected to an upper portion of the base portion 227. The bridge portion 228 is formed with a liquid guide chamber 229, and a lower portion of the base portion 227 is used for fixing the heat generating component 23. The top end of the liquid guide cavity 229 is communicated with the bottom end of the liquid storage cavity 11 in the liquid storage bin 1, and the bottom end of the liquid guide cavity 229 is communicated with the heating component 23.

The heating element 23 is used for adsorbing the liquid from the liquid storage cavity 11 and heating the atomized liquid. The heat generating assembly 23 includes a liquid guiding member 231 for guiding the liquid, and a heat generating member 232 for adsorbing the liquid and heating and atomizing the adsorbed liquid. The liquid guide 231 is preferably made of a porous material such as ceramic. The heat generating member 232 is preferably a metal heat generating chip, which is made of a foamed metal. Referring to fig. 6 and 7 together, the metal foam is a metal material having conductive properties and a microporous structure formed by fine metal strips through interweaving. Since the heat generating member 232 of the heat generating component 23 is made of foam metal with conductivity and microporous structure, the heat generating member 232 has the characteristics of oil guiding and heat generating atomization, so that the air passage through which the air flow flows does not need to adopt a design of passing around both sides of the liquid guiding member 231, but adopts a straight-through design. Therefore, when the user uses the heating assembly 23, the atomized gas of the heating member 232 can be directly sucked away, the whole air passage of the heating assembly 23 is kept clean and fresh all the time, the purity of the atomized gas is greatly improved, and the generation of condensate is effectively inhibited. The heating member 232 is made of a foam metal material instead of a conventional metal sheet or thick film printing paste, and the foam metal material can be cut into a required shape and embedded into the ceramic. Specifically, the heating element 232 may be fixed in the mold cavity, then the porous material such as ceramic is die-cast into the mold cavity, and then the die-cast heating element 232 and the liquid guiding element 231 are sintered to form the heating assembly 23 of an integrated structure.

In this embodiment, the liquid guiding member 231 has a hollow shape with two axial ends opened, and includes a first end 311 and a second end 312 which are substantially axially opposite to each other, a shoulder 313 provided between the first end 311 and the second end 312, and a peripheral wall 314 connecting the shoulder 313 and the second end 312. The lower end of the liquid guide chamber 229 of the upper frame 21 communicates with the shoulder 313 of the liquid guide 231 of the heat generating unit 23. The shoulder 313 and the peripheral wall 314 form a receiving space 315 that opens at the second end 312. In this embodiment, the shoulder 313 is provided as two symmetrical slopes that incline from the first end 311 to the second end 312, thereby increasing the contact area with the liquid in the reservoir chamber 11. The liquid from the liquid storage chamber 11 is first guided to the liquid guiding member 231 through the shoulder portion 313, and then absorbed, heated and atomized by the heat generating member 232 embedded in the liquid guiding member 231. The heat generating member 232 is partially exposed to the receiving space 315 of the liquid guiding member 231 and partially embedded in the liquid guiding member 231. Specifically, the non-heat generating region (liquid absorbing portion) of the heat generating member 232 is fixed in the liquid guiding member 231, the heat generating region 322 (heat generating portion) is suspended outside the liquid guiding member 231 (i.e., in the accommodating space 315), and the liquid guiding member 231 made of ceramic hardly absorbs heat of the heat generating member 232 when the heat generating member 232 operates, thereby improving the effective utilization rate of the heat generating heat. The heating member 232 is embedded into the liquid guiding member 231 along the whole length direction of the heating member to improve the connection tightness between the heating member 232 and the liquid guiding member 231, ensure the sufficient contact between the heating member 232 and the liquid guiding member 231 and avoid the problem of dry burning and even core pasting.

Specifically, the sheet-shaped heat generating member 232 of the present embodiment is disposed in the accommodating space 315 in a manner perpendicular to the second end 312. The microporous structure that the piece 232 that generates heat that is made by the foam metal has for the design of air flue need not pass around the both sides of ceramic drain 231, can adopt through design (see fig. 4), and at the in-process of suction, can directly siphoning away the atomizing gas of the piece 232 that generates heat, lets whole air flue remain clean, fresh and cool all the time, has improved the purity of the atomizing gas greatly, has effectively inhibited the condensate and has produced. A heat generating member 232 made of a foamed metal is disposed at a center position of the liquid guiding member 231. The heat generating member 232 divides the accommodating space 315 into two parts, forming a first air passage 323 and a second air passage 324 with the heat generating member 232 as a symmetrical plane. The air flow passing through the accommodating space 315 is divided by the heat generating member 232 into the first air path 323 and the second air path 324. Specifically, the heating element 232 changes the direction of the atomizing gas, so that the atomizing gas is divided towards two sides of the heating element 232, the condensate brought up during suction is blocked and absorbed by the liquid guiding element 231 on the peripheral side of the heating element 232, and the risk in the suction inlet along with the atomizing gas is reduced. In addition, the heat generating member 232 made of foam metal can atomize the liquid from the liquid storage chamber 11 more softly and the fragrance is purer due to its microporous structure; the metal foam heating member 232 is located at the center of the ceramic liquid guiding member 231, so that even if the heating member 232 heats oil, the oil can be absorbed by the ceramic liquid guiding member 231 on the side and atomized again, thereby reducing the gurgling noise and other problems when condensate is sucked.

Preferably, a central depression of the first end 311 of the liquid guide 231 of the heat generating component 23 forms a third air passage 325 for converging air flows from the first air passage 323 and the second air passage 324. The heat generating member 232 of the heat generating component 23 faces the bottom of the third air duct 325. In this embodiment, the third air duct 325 is substantially a hollow cylinder with two open ends. The width of the third air path 325 is substantially equal to the sum of the widths of the first air path 323 and the second air path 324 in a direction perpendicular to the axial direction of the atomizer 100 and perpendicular to the heat generating member 232. The width of the third air path 325 is smaller than the width of the first air path 323 or the width of the second air path 324 in a direction perpendicular to the axial direction of the atomizer 100 and parallel to the heat generating member 232.

Preferably, the height of the heat generating region 322 in a direction perpendicular to the second end 312 of the liquid guiding member 231 is not greater than the height of the accommodating space 315 in the direction. In addition, two bosses 326 are disposed on the shoulder 313 of the liquid guiding member 231 toward the inner side of the accommodating space 315, so as to enhance the stability of the heat generating member 232 in the accommodating space 315. In this embodiment, the heat generating member 232 further includes a first pin 327 and a second pin 328 respectively extending and guided through the peripheral wall 314 of the liquid guiding member 231 for electrically connecting the heat generating member 232 to the battery assembly.

One end of an air outlet channel 14 formed by the air duct 13 of the liquid storage bin 1 is communicated with the outside, and the other end is connected with the upper bracket 21.

The inner ring 62 of the second sealing sleeve 6 mounted on the bridge 228 abuts at the bottom end of the inner wall of the reservoir 1. The connecting portion 63 is provided with a second through hole 64 corresponding to the drainage cavity 229. The second through hole 64 is sized to fit the top end of drainage lumen 229.
